15 Claims. (Cl. 242-31) This invention relates to winding machines, andparticularly to machines for winding filling bobbins, cops, pims andsimilar packages of yarn for use in loom-shuttles or for other purposessuch as supplies for further transfer processes. By the term bobbin orcop as hereinafter used in the present specification and claims is meantany wound massof strand material, either textile or otherwise, built upin overlapping layers with the package growing by longitudinal or axialextension; and the term yarn as hereinafter employed is intended toapply to all kinds of strand materials.

In machines of the present type it has been the usual practice to employa reciprocating threadguide for traversing the strand to an extent lessthan the full length of the package and by gradually advancing the guideto dispose the yarn in conical chases whereof to build the -bobbin ofcylindrical form with a tapered end. The

conventional method of feeding the strand-guide along the length of thepackage consists in the use of a screw-threaded traverse-rod on whichthe guide is mounted with a nut engaging the threads on the rod andarranged to be rotated intermittently by a contact-member orprogression-wheel contacting with the periphery of the wound mass ateach rearward reciprocation of the rod. With this well known type oftraversing means the contact-wheel must engage frictionally with therotating bobbin to be turned thereby and it has been found in someinstances,

particularly in winding fine yarns such as rayon and other syntheticmaterials, that the contact of the progression-wheel with the bobbin hasa deleterious effect on the yarn. Stated briefly, the frictionalengagement of the contact-wheel with the surface of the winding causesan abrading action which roughens the fibers or otherwise damages thematerial sothat defects may appear in the fabric or other product inwhich the yarn is eventually incorporatd.-

To avoid any such injurious action by the contact of a progression-wheelwith the yarn on the winding package the present invention has for oneof its objects to provide meansfor advancing the strand-guide along thetraverse-rod without the use of such contact means.

Another object of the invention is to provide means for advancing thestrand-guide along the traverse-rod adapted to be actuatedintermittently by the reciprocatcry motion of the rod.

Another object of the invention is to provide a traversing mechanism ofthe type indicated in 55 which means connected to the guide engage thescrew-threads on the traverse-rod and the rod is intermittently rotatedto feed. the engaging means and thereby advance the guide longitudinallyof the rod.

, Another object of the invention is to provide a 5 traversing mechanismof the type indicated comprising ratchet-means actuated by thereciprocal tory motion of the traverse-rod to turn the latter to advancethe guide therealong.

Another object of the invention is to provide '10 a traversing mechanismof the type indicated having means for adjusting the ratchet-means toregulate the extent of turning motion of the traverse-rod within finelimits.

Another object of the invention is to provide 15 an improved traversingmechanism which may be applied to standard types of machines bysubstituting it for certain parts thereof without change in the generalconstruction of the machine.

Further objects of the invention are set forth in the followingspecification which describes a preferred form of construction of theimproved traversing means,'by way of example, as illustrated by theaccompanying drawings. 25

The present invention is herein illustrated and described as applied toa winding machine of a ll type similar to that disclosed in UnitedStates Letters Patent No. 946,831 granted January 18, 1910, topSimon W.Wardwell. In general, the machine comprises a frame or casing 2 mountedon legs or standards 8, as indicated in Fig. 1 of the present drawings,and arranged with a plurality of winding spindles 5 projecting from theside of the casing. Only one of the winding spindles is herein shown asbeing Journaled in bearings 5and 1 at opposite sides of the casing 2 anddriven from a horizontal shaft 8 Journaled therebelow with helicalgearsS and I5 connecting the drive. A second drive-shaft |5 carries ahelical gear |5 meshing with a gear |1 free to rotate on the spindle 5,the gear I5 being connected to drive the spindle through a clutch andthe gear l1 being similarly connected to drive a cylindrical cam 2|which is free to rotate on the spindle 5.

A horizontal traverse-rod 25 is mounted to slide longitudinally in abearing 24 on the side of the frame 2, its rearward end being connectedby a link 21 to a rocker-arm 28 mounted fast on a rock-shaft 25extending horizontally of the frame 2. The upper end of the rocker-arm28 carries a roller or bowl 85 engaging a helical groove 8| in the cam2|, by means of which the arm is oscillated during the rotation of thecam. The inner end of the link 21 may be con- V nected to the rocker-arm28 by a pin 52 engaging in any one of a series of holes 58 in the armwhereby the traverse-rod 25 is caused to be 'reciprocated from theoscillation of the arm and its extent of reciprocation may be adjustedin accordance with requirements.

The traverse-rod 25 is constructed in two axially-alined sections withits outer section 25 formed with helical screw-threads as shown mostclearly in Figs. 1 and 2. The inner end of the screw-threaded section25projects through a bore in a thimblelike sleeve 55 with the extremity ofthe rod reduced in diameter and riveted through a collar 55. The sleeveis counterbored at 81 to receive the collar 85 and a bushing 58 in thebore surrounds the outer end of the main section of the traverse-rod 25with a tapered pin 88 securing the sleeve and bushing thereto. By meansof this construction the outer threaded section 25 of the traverse-rodis connected in alinement with the main section 25 to be reciprocatedtherewith while permitting the section 25 to rotate with respect to themain section 25.

The outermost end of the threaded section 25 of the traverse-rod ismounted to slide in a sleeve 4 which is journaled in an outboard bearing44 formed as a part of a bracket 45. The bracket 45 is attached to theouter end of a horizontal arm or bracket 45 fastened to the side of themainframe 2, see Figs. 1 and 3. Referring particularly to Fig. 4 of thedrawings, the inner end of the sleeve 45 is reduced in diameter andscrewthreaded at 41 to receive a disk or wheel formed with ratchet-teeth5| on its periphery.

.The ratchet-wheel 55 abuts a shoulder on the .a pin or pivet 581 boreof the sleeve to accommodate its reciprocating motion.

' The ratchet-wheel 55 is arranged to be turned intermittently to rotatethe traverse-rod section 25 through the means of pawls carried by arocker-arm 55, to be described later. It will be noted by reference toFig.2 that the traverserod section 25 extends opposite to and parallelwith the axis of the winding spindle. 5 on which the package is wound.The winding spindle 5 may be of any preferred form and, as herein shown,it is provided with a tapered extension for receiving the tubular barrelof a wooden bobbin or yarn-receiver b on which the cop or bobbin B,represented by dot-and-dash lines, is wound.

The strand-guide 4 which is mounted on the threaded section 25 of thetraverse-rod is generally of conventional form as comprising abifurcated arm 55 having the ends of its bifurcations or legs connectedto sleeves 5| which are slidably mounted on the rod. Mounted between theends of the sleeves 5| is a longer sleeve 55, also free to slide on therod-section 25 and formed with a radial flange 55, see Fig. 3. Connectedto the side of the flange 55 is an elbow-shaped member 51 heldrotatively therewith by means of The member 51 is formed with alaterally-projecting arm or right-angle extension 55 through which isthreaded a stud 15 carrying a check-nut 1|. The stud 15 is also threadedthrough a lateral extension or flange 12 at the upper end of an arm 15forming part of a bifurcated element 15. .The arm 18 has its counterpartin an opposite arm 14 forming a fork therewith, the ends of both armsbeing provided with holes for receiving the threadedrod-extension 25which forms a support for the element. The lower end of the fork of theelement 15 is provided with an extension formed into a hook 15 loopedaround a horizontal rod 11 extending parallel with the rod-section 25and arranged therebelow with its ends supported in bearings at the innerand outer end of the bracket 45. By this form of construction of thecorrelated parts described above the element 15 is prevented fromturning on the traverse-rod extension 25 while being free to slidetherealong;

and the member 51 being connected to said element by the stud 15 is alsoheld from turning on the rod. The sleeve 55 is likewise prevented .fromturning on the rod-extension 25 through its connection with the member51 by means of the pin or rivet 55.

Referring to Figs. 2 and 5 of the drawings, a lever 55 is pivoted to theside of the member 51 by means of a stud 5| with its forward portionextending through the narrow opening between the flange 55 and member 51and also through a slot in the sleeve 55; the bottom edge of the leverbeing shaped to partially encircle the rodextension 25 and engage in thesquare-cut threads thereon. {ihelical spring 52 anchored to a lug 55 onthe member 51 has its opposite end connected to an upper arm 84 of thelever 85 whereby to normally maintain the lever in engagement with thethreads on the rod-section 25. The rearward arm 85 of the lever 55 isformed with a finger-piece 55 arranged opposite to a similarfinger-piece 51 on the member 51, this arrangement providing formanually operating the lever 55 in the manner of shears by pressing thefingers on the two finger-pieces 85 and 51 to lift the forward portionof the lever to free the rod-extension 26. This manual release of thelever 80 from the screw-threads is provided for the purpose of returningthe strand-guide 4 to first position to start winding a freshpackage bysliding it rearwardly of the rod-extension 26.

The strand-guide 4 may be of usual construction in the form of a groovedporcelain element fastened, to the guide-arm 60 by a screw 62, thestrand of yarn or thread 1/ being adapted to lead downwardly through thegroove in the guide in the manner indicated by dot-and-dash lines 'inFig. 5 to cause it to be wound onto the bobbin B which rotates in thedirection indicated by the, arrow in this view. In order to restrain thestrand-guide 4 from rubbing against the packjustable to position theguide in close relation to,

but slightly spaced from, the periphery of the bobbin B.

The ratchet-mechanism for turning the traverse-rod extension 26comprises the rocker-arm or lever 58, previously referred to, which isconnected by a hook-ended rod or link 88 to an actuating lever 90. Theactuating lever 90 is pivoted on a stud or pin 9I passing through abearing in an arm 92 extending horizontally inward from the bracket 45,previously referred to as fastened to the end of the bracket 46. Theactuatinglever 90 is of bifurcated shape, as shown in Fig. 2 of .thedrawings, having a forward arm 93 formed with a hole at its end intowhich the hooked end of the link 88 is engaged, and an opposite parallelarm 95 projecting upwardly with.

its terminal portion located adjacent the side of the traverse-rodextension 26. The upper extremity of the arm 95 is inclined to the leftas viewed in Fig. 3, and formed with an arcuate edge 96 adapted to beengaged by the side of a collar I 00 fixed to the traverse-rod section26, this engagement being for the purpose of rocking the lever 90 toactuate the rocker-arm 58. The collar I00 may be split to adapt it to beclamped on the rod-section 26 by means of a binder-screw IIlI, therebyproviding for its adjustment longitudinally of the rod to regulate theextent of its contact with the actuating lever 90. The actuating lever90 is normally maintained in the position indicated by full lines inFig. 3 by means of a helical spring I02 connected to its arm 93 andsuspended from the upper bent end of a rod I03. The lower end of the rodI03 is screwed into the supporting arm 92 and held fast by a check-nutI04. A stud I05 threaded through a lug I06 on the under side of the arm92 is arranged with its end engaging a downwardly-extending finger I01on the actuating lever 90, whereby to limit the rocking motion of thelever under the action of the spring I02. By turning the stud I05 theposition of the arm 95 may be adjusted in relation to the stroke of thecollar I00 on the rod-extension 26, thereby providing a relatively fineadjustment for regulating the extent of rocking moagainst the side ofthe lug I06 to maintain thestud in its adjusted position. A secondhelical spring I09 hooked through the outer extremity of the arm 93 ofthe lever 90 is connected at its upper end to the pawl-carrying arm 58whereby 2,217,140 it from engagement with the screw-threads on toprevent lost motion or play of the link 88 in its connection with the.arm 58 and the lever 90.

As shown most clearly in Fig. 2 of the present drawings, theratchet-operating arm or lever 68 carries two pawls H0 and III arrangedside by side and pivoted on a stud II2 fastened to the side of the arm.The pawls H0 and III have pointed toes adapted to engage with the teeth5| onthe ratchet-wheel 50, a bifurcated leaf-spring II3 being providedto act against thepawls. The spring, H3 is fastened to an elbow-shapedplate I I4 secured to the side of the arm 68 by a nut II5 on the studH2. The spring I I8 has its rearward portion riveted to thelaterally-extending portion of the plate II4 with its two fingersextending forwardly to bear against the' top of the two pawls H0 andIII; It will be noted by reference to Figs. 2 and '6 that the pointedtoe of the pawl II 0 is positioned slightly to the rear on the toe ofthe pawl III or, in other words, the pawl H0 is slightly shorter thanthe pawl III, the difference in length being equal to half the length ofa tooth on the ratchet-wheel. The purpose of this form of constructionis to provide that the ratchet-mechanism may be adjusted with extremeaccuracy and fineness to vary the turning motion of theratchet-wheel-50, for example by the distance of one-half of one toothon its periphery; it being understood that when the arm 95 of the lever90 is struck by the collar I00 the lever will be rocked 95 of the lever90 will be released, whereby the spring I02 will rock the lever to causethe link 88 to raise the arm 58. This upward oscillation of the arm 58then causes the pawls, one or the other of them in accordance with whichone is engaged with a tooth on the ratchet-wheel 50, to turn the wheelin a clockwise direction as viewed in Figs. 6 and 7.

In order that under the rapid oscillation of the arm 58 in turning therod-section 26 the momentum of the rod and its connected sleeve 40 maynot cause the parts to rotate beyond the required extent, means areprovided for frictionally braking the movement of the sleeve 40.Referring to Fig. 3, a friction disk H6 is held in a bore in the bearing44 with a helical'spring I I1 tending to press it against the peripheryof the sleeve 40. A screw II8 threaded into the upper end of the boremaintains the spring III under compression and may be adjusted toregulate-the friction of the disk on the sleeve 40, a check-nut 9 beingprovided on the screw 1 I8 to secure the latter in its adjustedposition.

The construction and arrangement of the traverse-mechanism of thewinding machine having been described in detail, its method of operationis explained as follows: At the start of the winding the thread-guide 4is placed at the inner end of the traverse-rod section 26 by pressing onthe finger-pieces 86 and 81 to release the forward end of the lever 80from the threads ,on the rod and sliding the guide-arm rearwardly alongthe latter. To prepare the machine for operation a bobbin b or otheryarn-receiver is placed on the spindle 5 and theend of the strand ofyarn 3! leading from a suitable source of supply is attached to thereceiver in any convenient manner after leading it through the groove inthe strand-guide 4. v

The machine is started to operate by rocking the rod TI to clutch thegear I0 with the spindle 6 and the gear I1 with the cam H in accordancewith the arrangement shown in the patent referred to previously; itbeing understood that the shafts 8 and II for driving these last-namedgears are rotated continuously from a suitable source of power. As thespindle 6 is rotated the yarn will be wound onto the bobbin 1) and thecam 2| will actuate the rocker-arm 28 to reciprocate the traverse-rod 26and its connected section 26 longitudinally of the winding spindle. Itwill be understood that the extent of reciprocation of the traverse-rod26, and thereby the thread-guide 4 carried on the rod-extension 26, isequal to only a fraction of the full length of the bobbin to' be woundand consequently the yarn will be deposited on the bobbin b inrelatively short layers. Each time the traverse-rod section 26 movesoutwardly away from the frame 2 the collar I00 will ride against thecurved end 86 of the lever 90 to rock the latter in a clockwisedirection as viewed in Figs. 1 and 3. This rocking motion of the lever90, indicated by the full and dash lines in Fig. 3, will cause its arm83 to draw down the pawl-arm 58 which is connected thereto by means ofthe link 88, see Fig". 7. The pawls I I0 and I I I are thereby retractedover the teeth 6 6| of the ratchet-wheel 60 and after the collar I00reaches the outward end of its reciprocatory motion with the rod-section26 it will recede from the lever allowing the latter to be rocked backin the opposite direction under the tension of the spring I02. Thisrearward rocking motion of the lever 60 will cause its arm 83 to raisethe link 88 and thereby rock the arm 68 in a clockwise direction asviewed in Figs. 6 and 7. Therefore, since one or the other of the pawlsH0 and III will be in engagement with a tooth on the ratchet-wheel 50the latter will be rotated through a part of a revolution to turn thetraverse-rod section 26 with it by means of its key connection at 63wtih the sleeve 40, see Fig. 4.

The turning motion thus imparted to the traverse-rod section 26 willcause its threads to act through the lever 80 engaged therewith toadvance the arm 60 and strand-guide 4 a certain distance outwardly alongthe rod. The extent of this advance or feed oi the thread-guide isusually equal to about the thickness of a strand of yarn and mayberegulated by adjusting the collar I00 on the rod section 26; a lineradjustment being secured by turning the stud I05 to locate the lever 90in such position as to control the extent of its movement under theaction of the collar I00.

The winding proceeds in this manner with the strand-guide 4 depositingthe yarn in relatively short layers or courses which build up in conicalformation as indicated by the dot-and-dash lines in Figs. 2 and 3. Eachtime the threaded rodsection 26 is rotated the strand-guide 4 will beadvanced to step the next-wound layer in advance of a precedingly-laidcourse of the yarn and in this way the bobbin grows by longitudinalextensionuntil the guide 4 has been fed outwardly along'the traverse-rodsection 26 to a point adjacent the end of the bobbin 1). At thisjuncture suitable stop-motion devices, not herein shown or described,come into action to arrest the operation of the machine by declutchingthe gears I0 and I! to permit them to idle. It has been stated that asthe traverse-rod section 26 is intermittently rotated frictionalresistance to the turning of the sleeve 40 connected therewith, underthe braking action 01' the disk H6 and spring III, prevents overrunningoi! the rod and thus the advance or feed of the strand-guide 4 ismaintained constant within prescribed limits. The present improvedtraversing mechanism thus operates to produce accurately formed bobbinsor packages with the yarn laid in even courses, and without imposing anyinjurious action on the yarn by a progression-wheel or contact-member.Consequently, the finest and most delicate mate-' rials may be woundsuccessfully without abrading or lnjurying the fibers.

It will be observed further that the present invention provides a noveland simple mechanism for eliminating the contact-means orprogression-wheel usually considered necessary for use in machines ofthe present type.
